Nkhumba Yophika Yozizira Yozizira
| Chiyambi cha malonda | Zopangira zimachokera ku nyumba zophera nyama komanso mabizinesi olembetsa ku China.Zopangira zochokera kunja zimachokera ku France, Spain, Netherlands, ndi zina. |
| kufotokoza | Zambiri, vomerezani mwambo |
| Mawonekedwe | Chiŵerengero cha mafuta kuonda ndi 3:7, mafuta koma osati mafuta. |
| Ikani tchanelo | Oyenera kukonza chakudya, malo odyera ndi mafakitale ena. |
| Zosungirako | Cryopreservation pansi -18 ℃ |
Nyama yowuma imatanthawuza nyama yomwe yaphedwa, yoziziritsidwa kale kuchotsa asidi, kuzizira, kenako kusungidwa pansi -18 ° C, ndipo kutentha kwakuya kwa nyama kumakhala pansi -6 ° C.Nyama yowunda kwambiri nthawi zambiri imaundana pa -28°C mpaka -40°C, ndipo ubwino wa nyama ndi kakomedwe kake sizosiyana kwambiri ndi nyama yatsopano kapena yozizira.
Ngati atazizira pa kutentha kochepa, ubwino ndi kukoma kwa nyama kumasiyana kwambiri, chifukwa chake anthu ambiri amaganiza kuti nyama yowundana si yokoma.Komabe, mitundu iwiri ya nyama yozizira imakhala ndi nthawi yayitali, choncho imagwiritsidwa ntchito kwambiri.
Mphamvu ya tizilombo
1. Zosiyanasiyana zamakina achilengedwe zimachepa pang'onopang'ono pakagayidwe kazinthu zazing'onoting'ono pa kutentha kochepa, kotero kukula ndi kubereka kwa tizilombo kumachepa pang'onopang'ono.
2. Pamene kutentha kumatsika pansi pa malo oundana, madzi a tizilombo toyambitsa matenda ndi malo ozungulira amaundana, zomwe zimawonjezera kukhuthala kwa cytoplasm, kumawonjezera kuchuluka kwa electrolyte, kusintha pH mtengo ndi colloidal state ya maselo, ndi denatures the maselo.Kuvulala, kusintha kumeneku kwa mkati ndi kunja kwa chilengedwe ndi chifukwa chachindunji cha kulepheretsa kapena imfa ya tizilombo toyambitsa matenda.
Mphamvu ya michere
Kutentha kochepa sikulepheretsa enzyme, ndipo puloteniyo imathabe kukhala ndi gawo la ntchito yake, kotero kuti catalysis siimaima, koma imayenda pang'onopang'ono.Mwachitsanzo, trypsin akadali ndi mphamvu yofooka pa -30 ° C, ndipo ma enzymes a lipolytic amatha kuyambitsa mafuta hydrolysis pa -20 ° C.Nthawi zambiri, ntchito ya enzyme imatha kuchepetsedwa mpaka pang'ono pa -18 ° C.Choncho, kusungirako kutentha kochepa kumatha kuwonjezera nthawi yosungira nyama.
